The frustration with President Barack Obama over his tax cut compromise was palpable and even profane at Thursday&rsquo;s House Democratic Caucus meeting.

One unidentified lawmaker went so far as to mutter &ldquo;f--- the president&rdquo; while Rep. Shelley Berkley was defending the package the president negotiated with Republicans. Berkley confirmed the incident, although she declined to name the specific lawmaker.

&ldquo;It wasn&rsquo;t loud,&rdquo; the Nevada Democrat said. &ldquo;It was just expressing frustration from a very frustrated Member.&rdquo;

Rep. Jerrold Nadler (N.Y.) was also overheard saying that &ldquo;we can&rsquo;t trust him&rdquo; not to cave to Republicans and extend the tax cuts again in two years, according to a Democratic source.

The anger aimed at the bill was widespread. As Democrats moved to block the bill from coming up on the floor, chants of &ldquo;Just say no!&rdquo; could be heard by reporters outside the room.

Berkley is one of the few Democrats publicly supporting the package. While she said it wasn&rsquo;t necessarily how she would have written it, the bill should go forward in her estimation because it is &ldquo;chock full&rdquo; of tax cuts that will help the working class in her state.

&ldquo;I&rsquo;m not willing to play Russian roulette to see who blinks first,&rdquo; Berkley said.
